Store API keys properly on LocalStack with Secrets Manager and a customer-managed KMS key. Build a Lambda that reads the secret at request time, rotate it, and watch the new value go live without a redeploy.
Build a real Step Functions workflow on LocalStack: validate, fan out across parallel Lambdas, then notify via SNS. Trigger it manually, then wire it to an EventBridge schedule and watch it fire automatically.
Build a real async job pipeline on LocalStack with an SNS topic, an SQS queue, and a DLQ. Watch a poison message retry three times, land in the DLQ, and inspect what to do next.
After using LocalStack for years and publishing the first four parts of my local AWS series, Floci caught my eye: MIT licensed, no account required, and built around the same localhost:4566 workflow.
Put a real HTTP API in front of the URL shortener from Part 2. API Gateway HTTP API, Lambda, a small JWT authoriser, and curl-based verification running on LocalStack.
Wire Lambda to S3 upload events on LocalStack. Upload a photo, get a 256px thumbnail in another bucket automatically, and learn the `localhost.localstack.cloud` networking gotcha before it wastes an evening.
Build the DynamoDB layer for a URL shortener on LocalStack: table design, atomic click counters, fixture loading, and a small Node CLI you can reuse. Part 3 detours into Lambda, then Part 4 wraps the shortener in an HTTP API.
Build the first real app in the LocalStack series: an S3 bucket, CORS, presigned PUT URLs, and a tiny browser photo uploader.
Docker has shipped a Toolkit and Catalog for the Model Context Protocol, plus a Gateway that fronts the lot. Containerised MCP servers, signed images, OAuth handled in-browser, and Profile Templates added in March 2026. Here's what it actually does and where it fits.
Photo uploads, a URL shortener, async jobs, scheduled workflows — all running on LocalStack on your laptop, all free. Part 0 of a 9-part series walks through the setup: Docker, auth token, AWS CLI, init-hooks. About 30 minutes from a fresh laptop to a working S3 bucket.
Fedora 44 released 28 April 2026. GNOME 50, kernel 6.19, NTSYNC for Wine, GCC 16, Ruby 4.0, CMake 4 with ninja. What changed and how to upgrade safely.
Originally called Clawdbot, now rebranded as OpenClaw, it's an open-source AI that actually does things instead of just chatting. So this weekend, I set it up on my Proxmox homelab.
